Title: Improvements in or relating to electric motor control systems
IPC: H02P1/54
Filed: 1929-03-06
Abstract: 330,300. General Electric Co., Ltd., Saunders, C. W., Wilson, H. W., and Emms, S. A. G. March 6, 1929. Selective distant control systems.-A control storage device is arranged so that closure of buttons 218 for starting corresponding electric motors cause the motors to be started in succession by a common starting means, the control for any motor being stored until the starting means is available. Closure of any button 218 energizes a contactor 216 which maintains itself over contacts 222 and causes a solenoid 204 to ratchet an arm 207 over contacts 208 until it engages one that is connected to a closed contactor 216, whereupon a relay 212 is energized to open the circuit of solenoid 204 and a relay 232 is energized to close contacts that effect connection of the corresponding motor to the common starting means as soon as it is available. When this occurs interlocks associated with that motor interrupt the maintaining circuit of the contact or 216, which thereupon opens and de-energizes relays 212, 232, closing of the contacts of the former allows the arm 207 to proceed to another stud 208 if any other contactor 216 is closed, and subsequently the corresponding motor is connected to the common starting means when it becomes available.

Title: An improved method of inhibiting gum formation in lowboiling hydrocarbon oils and products obtained thereby
IPC: C10L1/00
Filed: 1932-03-11
Abstract: Low-boiling hydrocarbons are prevented from gumming by adding both a colourless inhibitor and an inhibitor which is a dye; inhibition is therefore effective at least as long as the liquids are coloured. The inhibitor may be added as a solution in benzene or other solvent. Colourless inhibitors specified are a -naphthol, secondary amyl p-amino-phenol, hexyl-p-phenylene diamine, methyl-aniline, toluidine, aniline, phenol, o, m, p cresol, tricresol, and anthraquinone.  For example, gasolene may be treated with 0,010 per cent of a -naphthol and 0,001 per cent of the blue indophenol formed by the condensation of a - or b -naphthol with p-nitroso-dimethyl aniline; or with 0,020 per cent of tricresol and 0,003 per cent of the red indophenol obtained by condensing diphenylamine with p-nitroso-phenol. Specification 385,066 is referred to.

Abstract: 267,974. Budd Wheel Co., (Assignees of Ragsdale, E. J. W.). March 20, 1926, [Convention date]. Shoes acting on drums; compensating for wear. -A braking mechanism comprises a connecting member extending from the portion of the shoe to which the braking force is applied to an operating member and an adjusting device automatically operative to extend the connection upon a predetermined movement of the shoe. A brake operated by toggle links 22, 23 is automatically compensated for wear on abnormal movement of a shoe by rotation of a cam sleeve 30, Fig. 1, adapted to increase the distance between the shoe and the link pivot 25. Rotation of the sleeve 30 is brought about by a pawl 43, Fig. 3, fixed to the link 22 and engaging, by means of an inturned end, teeth 32 on the periphery of the sleeve. This pawl, on operation of the brake moves up the inclined surface of a tooth and when sufficient wear has taken place slips into engagement with the next tooth and rotates the sleeve as the brake is released. The sleeve is held in the new position by teeth 31, in alignment with and equal in number to, the teeth 32 and ananged on the end face of the sleeve so abutting the end of the brake shoe which is formed with co-operating teeth. Rotation of the sleeve causes a pair of cams 33 on the outer face thereof and extending through arcs of 180‹. to ride up complemental cam surfaces on collars 36 provided on the link pivot 25, thereby increasing the distance between this pivot and the shoe. The collars 36 are maintained in engagement with the cams 33 by a spring 42 mounted on a stem 37 projecting from the pivot 25 through openings in the sleeve 30 and in the end of the brake shoe. The spring 42 abuts against the end of a recess in the brake shoe and a collar pinned on the stem 37. Both shoes may be provided with this automatic adjusting means. Each toggle link 22, 23, Fig. 1, consists of a pair of parallel members arranged on opposite sides of the brake shoe ends and a plate 12 and pivoted together on a pin 24 guided in a slot 27 in the plate 12 which is bolted to the axle casing and to which are pivoted the brake shoes. The brake operating cam 20 acts on an extension of the link 22. Springs 17, 28 return the brake to inoperative position.

Title: Improvements in the combustion of liquid and like fuel
IPC: F23C99/00
Filed: 1920-03-19
Abstract: 140,468. Good Inventions Co., (Assignees of Good, J.). June 6, 1916, [Convention date]. Spray burners.-Liquid-fuels are burned to obtain high temperatures by being sprayed into a confined passage to which air is admitted in a proportion suited to complete combustion in the passage, and so that it gradually joins the spray stream, thus avoiding the formation of an explosive mixture where ignition of the mixture takes place. Liquid-fuel from a nozzle 5 is sprayed by an air nozzle 4 past an igniter 14 through an inlet chamber 11 having a star-shaped partitioning-device 12. Air from an injector 9 is introduced tangentially to the chamber 11 and serves to envelop the spray and effect complete combustion in the flame casing 1 which is surrounded by a box 3 which constitutes a vaporizer for an automobile engine. In another form, Fig. 5, the spray-producing means is constituted by a Venturi tube 7 supplied with oil from a nozzle 8, the air from a pipe 15 passing partly through the Venturi tube 7 and partly through a valve-controlled pipe 16 to a star-shaped member 17 which assists in preserving the separation of the streams of air and spray and serves the purpose of a vaporizer. Reference has been directed by the Comptroller to Specifications 106,812 and 107,571.
